Important: The pressure sensor is mounted on a Schrader-type valve. Do not recover the refrigerant from the A/C system when replacing this sensor.

1. Disconnect the electrical connection from the sensor.
2. Remove the following components:

•	The switch

•	The O-ring seal

1. Lubricate the O-ring using 525 refrigerant oil.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the following components:

•	The new O-ring seal

•	The switch

Tighten
Tighten the sensor to 12 N·m (9 lb ft).

3. Connect the electrical connection to the switch.
